Abstract

A battery pack assembly includes an array of individual electrochemical cells electrically connected to one another. The array of individual electrochemical cells is embedded and encapsulated by a matrix of conformable material and the matrix of conformable material provides a protective outer shell. A sensor is electrically connected to the array.

First claim

The invention claimed is:

1. A battery pack assembly comprising:
an array of individual electrochemical cells electrically connected to one another, the array of individual electrochemical cells being surrounded and encapsulated by a matrix of conformable material, the matrix of conformable material further providing a protective outer shell, the protective outer shell including a through opening; and
an electronic component disposed in the through opening,
wherein the array of individual electrochemical cells is arranged to be electrically connected to the electronic component.

2. The battery pack assembly of claim 1 , wherein the electronic component is a physiological sensor.

3. The battery pack assembly of claim 1 , wherein the electronic component is a heart rate sensor.

4. The battery pack assembly of claim 1 , wherein the electronic component is a temperature sensor.

5. The battery pack assembly of claim 1 , further comprising a drug delivery system that is activated by a signal from the electronic component.

6. The battery pack assembly of claim 1 , wherein the flexible outer shell comprises an outer shell material including one or more of the following:
a failure stretch ratio of 1.1 to 1.8 and
an ultimate tensile strength between 1 and 50 Mpa.

7. The battery pack assembly of claim 1 , wherein the outer shell material comprises an elastomer.

8. The battery pack assembly of claim 1 , wherein the outer shell material is laminated around the individual electrochemical cells.

9. The battery pack assembly of claim 1 , wherein the outer shell material comprises an adhesive on one side.

10. The battery pack assembly of claim 1 , wherein the outer shell material is molded around the electrochemical cells.

11. The battery pack assembly of claim 1 , wherein the outer shell material comprises a hardness of between HOOO-S 10 and 90A.

12. The battery pack assembly of claim 1 , wherein the outer shell material comprises an elongation break between 10% and 1,000%.

13. A battery pack assembly comprising:
an array of individual electrochemical cells electrically connected with one another, each individual electrochemical cell in the array being surrounded and encapsulated by a matrix of conformable material that forms a flexible outer shell; and
an electronic component operably connected to the array of individual electrochemical cells, the electronic component also being surrounded and encapsulated by the matrix of conformable material,
wherein the matrix of conformable material comprises a material having a hardness between HOO-5 and 30A.

14. The conformable battery pack assembly of claim 13 , wherein the electronic component comprises one or more of a processor, a microprocessor, a signal processor, an integrated circuit, a display, a capacitor, a resistor, a transistor, a medical application device such as a glucose delivery device or an automatic defibrillator, a global positioning system (GPS) receiver, a sensor (such as a biometric sensor, a temperature sensor, an accelerometer, a moisture sensor), or an antenna.

15. The conformable battery pack assembly of claim 13 , wherein the electronic component is operably connected to a face of one electrochemical cell in the array of individual electrochemical cells.
